Disclosure: Purgo Labs is our affiliate partner, and so is True Peptides (referral link only, no code). Scores come from the public rubric, which has no partnership input.
Research use only. Compound Review scores vendors on documentation — laboratory certificates, lot records, pricing and company identity. Nothing on this page is guidance on human or veterinary use, dosing or health outcomes.

What we found at True Peptides
Read 1 October 2026 on the vendor's own pages
The documentation is better than most launches: a named lab, a lot on every certificate and on the product page beside the price, measured content, an open database and a card rail. What it lacks is everything that takes time or a decision to publish — a review record, a verifiable certificate at the lab, a company name and address, and an accreditation it can point to. 6/10 on the rubric today; the four withheld points are the ones a new vendor earns by existing for a while and by printing who it is.

Could not verify · flags
?The certificate at the lab — PDFs are served from the vendor's own CDN, and Optiq Health Labs' site offers Login/Sign Up but no public lookup we could find; the 'scan to verify' QR on the report could not be resolved.
?Who is selling — the terms say 'True Peptides, a California limited liability company located in Irvine, California' with no registered name and no street address on any page.
?Any independent review record — no Trustpilot profile exists for true-peptides.com (1 Oct 2026). Do not confuse it with True Peptide Labs (truepeptidelabs.com, Palm Beach Gardens FL, 4.3 across 70 reviews) — a separate company with its own phone number and catalog — or with truepeptides-usa.com and truesciencepeptides.com.
?The accreditation claim — 'every result is from an accredited third-party facility' names no accreditation body or certificate.
!A very new store: terms effective 10 Aug 2026, first certificates 12 Aug 2026, no review history anywhere yet. Scores will move as the record builds.
!Several sizes on backorder when read (BPC-157 5mg, TB-500 10mg, GHK-Cu 100mg, Ipamorelin 5mg, Tesamorelin 5mg).
!Catalog includes retatrutide (10–40mg) sold as research material.
!Our partner link (?ref=health) tracks the referral but carries no discount; the vendor sets up a customer code on request and we will print one only when it exists and is tested.
'True Peptides, a California limited liability company located in Irvine, California' — terms of service, 10 Aug 2026. No registered entity name, no street address, no phone; contact is a web form (1 Oct 2026).
No lab-side lookup for this reportWhere we opened it Transcribed by Compound Review; the laboratory's report is the record.
Net content 9.89 mg/vial (99% of label). Lab lookup not available; QR unverified.
Where True Peptides ranks by compound
True Peptides appears in 6 of our compound rankings. Each ranking orders every scored vendor that sells the compound by rubric score, then verified price per mg.
2026-10-016/10 — first assessment (rubric v2); not awarded: lab-hosted (vendor CDN, no lab lookup), review-base (no Trustpilot profile), claims-consistent ('accredited facility' with no body named), identity (no entity name or address) — net content 9.89mg on a 10mg label
Purgo Labs: the caveat
Smaller independent review base than several competitors (80 reviews). The catalog is peptide-focused, so researchers also working with SARMs or broader research chemicals will need a second supplier.
True Peptides: the caveat
No Trustpilot profile exists for true-peptides.com (checked 1 Oct 2026). The 4.3-star 'True Peptide Labs' profile belongs to truepeptidelabs.com, a separate Florida company; truepeptides-usa.com and truesciencepeptides.com are different vendors too — so there is no independent review record yet. The terms name only 'True Peptides, a California limited liability company located in Irvine' — no registered entity name and no street address. Certificates are served from the vendor's own CDN; the certificate carries a 'scan to verify' QR but Optiq Health Labs shows no public lookup, so we could not check the report at the lab. The site says results come from 'an accredited third-party facility' without naming the accreditation or certifying body. Several sizes were on backorder when read (BPC-157 5mg, TB-500 10mg, GHK-Cu 100mg). The affiliate ref is a 'health' link; it tracks the referral but gives the buyer no discount.

Purgo Labs 10/10
True Peptides is an affiliate partner (referral link only, no code); we point you to our top-scored partner instead. Purgo Labs holds every rubric point — certificates checkable at the lab, measured net content per lot — and is cheaper after codes on 6 of 6 like-for-like vials.

Purgo Labs, on the evidence: 10/10 rubric points against 6/10. True Peptides is stronger on 2 points listed below. Every point is a fact you can check on either vendor's site; both are scored by the same published rubric.
Is True Peptides legit?
True Peptides scores 6/10 on our rubric, has no independently viewable review record, and names its lab (Optiq Health Labs). Caveat: No Trustpilot profile exists for true-peptides.com (checked 1 Oct 2026). The 4.3-star 'True Peptide Labs' profile belongs to truepeptidelabs.com, a separate Florida company; truepeptides-usa.com and truesciencepeptides.com are different vendors too — so there is no independent review record yet. The terms name only 'True Peptides, a California limited liability company located in Irvine' — no registered entity name and no street address. Certificates are served from the vendor's own CDN; the certificate carries a 'scan to verify' QR but Optiq Health Labs shows no public lookup, so we could not check the report at the lab. The site says results come from 'an accredited third-party facility' without naming the accreditation or certifying body. Several sizes were on backorder when read (BPC-157 5mg, TB-500 10mg, GHK-Cu 100mg). The affiliate ref is a 'health' link; it tracks the referral but gives the buyer no discount.
Which is cheaper, Purgo Labs or True Peptides?
On the 6 compound-and-size rows where we have dated prices from both, True Peptides lists lower on 0 and Purgo Labs on 6. Purgo's list prices drop 20% with code HEALTH.
Do you earn money from either vendor?
Purgo Labs is our affiliate partner and we earn a commission on referred orders, as we do from True Peptides. Scores come from the rubric, which has no partnership input, and the ordering rule on our scoreboard is disclosed.
